* Fixes #1317 - arm thb operand.shift.value For a more detailed description, see issue #1317. Release 4.0.0 introduced a new field for ARM operands: `operand.mem.lshift`. This field was supposed to be a bug fix for #246. The #246 issue has been fixed in the meantime and the proper shift value was stored in `operand.shift.value`. The 4.0.0 changes created a regression in which `operand.shift.value` was not set for a `tbh [r0, r1, lsl #1]` instruction on ARM and the value was set in a `operand.mem.lshift` field instead. As the regression broke some of users codebase (e.g. in [manticore](https://github.com/trailofbits/manticore/pull/1312) project), we fix it by setting `operand.shift.value` back again. As a result, the shift value is set in two fields: `operand.shift.value` and `operand.mem.lshift`. As the `operand.shift` also stores a `.type` field, we might want to deprecate `operand.mem.lshift` in the future. * Add changelog stub
